Don't trust everything the "experts" write

Contradictory information is all I kept running into when I was researching the Model 24. Hence my desire to write a book on them. Some of the historical information will likely never have a resolution.

For what it's worth, the 1918 is likely a typo. As far as I'm concerned, 1939 is the correct date for the start of the Stevens Model 22-410. Savage says 1939 in their literature, and if it was made in 1938 why didn't it appear in the 1939 catalog? Mostly because 1939 was the 75th anniversary year for the J Stevens Arms Co and the production of many new models began in that year and appear in the 1939 Stevens catalog. However the Model 22-410 does not appear until the 1940 Stevens catalog. With the entire line of Stevens/Savage combination guns, production of the next year's gun began the year before. Kinda like buying a 2014 car in late 2013.
